Update -20121116- New Features in my software.Well, The dynamic level setting, was to complicated and unnecessary. The better way to detect events that helps with event visualisation is more sensitive. Even the small ones can be counted .This has also simplified the interface controls.

A simpler interface

A collection of shapes and sizes

Update -20121114- New Features in my software.The interface now has dynamic level setting so that only high level events are triggered. Found a better way to detect events, helps with event visualisation . Added a Pingo Meter to the right hand side. ...

Update -20121112- New Features in my software.
The interface now has dynamic level setting so that only high level events are triggered. Also added a colourgram counter. A few more features in mind....

Update -20121025 - Mostly small and a few large meteors

Update 20121023 - If you don't want to do the programing with my little script.Then this is the software that the big guys are using , ARGO can be found herehttp://www.sdradio.eu/weaksignals/argo/index.html
It works with the Spaceweather audio stream just as mine does. Have fun......

UPDate: 20121022 - While watching the Audio trace from Space Weather Radio, this large burst happened by. Not sure what type of burst this was, usually they are spikes.

Large dispersed meteor trail....

Original post -

Remember my post "Fun With Geminids 2010". It was a bit complicated to get working.
I have been using Processing.org software lately, lots of fun. There are a few examples of how to show an audio spectra gram in real time.

﻿﻿ I wrapped a simple interface and triggered image saver around it.
﻿
﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿I have it running now, but the big meteors just don't want to happen, so here's a few I have captured during testing.

Just beware it will create a lot of images if the sensitivity is to low.And if you make a lot of noise, whistle or speak, it will trigger also.

You will need to be vwary vwary quite when hunting radio meteors....

How to make for your self - Download Processing.org software, load the following text into a new sketch and save. Make a data directory under this sketch folder. Then run it.
The images appear in the sketch folder.

// wrap back to the first column when we get to the end if (col == colmax) { col = 0; }

// Draw points. // leftedge is the column in the ring-filled array that is drawn at the extreme left // start from there, and draw to the end of the array for (int i = 0; i &lt; colmax-leftedge; i++) { for (int j = 0; j &lt; rowmax; j++) { // // sgwt =(sgram[j][i+leftedge])-(sgramb[j][255]); //stroke(sgwt); stroke(sgram[j][i+leftedge]); // point(i,height-j); //rect(i,height-j,2,2); } } // Draw the rest of the image as the beginning of the array (up to leftedge) for (int i = 0; i &lt; leftedge; i++) { for (int j = 0; j &lt; rowmax; j++) { // stroke(sgram[j][i]); point(i+colmax-leftedge,height-j); //rect(i+colmax-leftedge,height-j,2,2); } } // Next time around, we move the left edge over by one, to have the whole thing // scroll left leftedge = leftedge + 1; // Make sure it wraps around if (leftedge == colmax) { leftedge = 0; }
